The Mediterranean basin: A population genetic study based on 25 X-chromosome SNPs

The X-chromosome has valuable characteristics for population genetic studies. In order to investigate the genetics of the human Mediterranean populations further, we developed a 25 X-chromosome SNP-multiplex typing system. The system was based on PCR multiplex amplification and subsequent multiplex single base extension with the SNaPshot reaction, capillary electrophoresis and multicolor fluorescence detection.We investigated 11 Mediterranean populations with the 25 X-chromosome SNPs. A high overall homogeneity was found among the Mediterranean populations except for Moroccans, who differed genetically from the rest of the populations in the Mediterranean area. This result supports the hypothesis of a low incidence of the south-north genetic interchange at the western shores of the Mediterranean basin. A low genetic distance was found between populations in the Middle East and the western part of the Mediterranean area most likely reflecting the strong effect of the Neolithic wave.A certain level of background linkage disequilibrium among the 25 SNPs on the X-chromosome in Ibiza and Cosenza was observed, possibly as a consequence of their demographic history.     

Lessons learned from inter-laboratory studies of carbon isotope analysis of honey

Forensic application of carbon isotope ratio measurements of honey and honey protein to investigate the degree of adulteration with high fructose corn syrup or other C₄ plant sugars is well established. These measurements must use methods that exhibit suitable performance criteria, particularly with regard to measurement uncertainty and traceability – low levels of adulteration can only be detected by methods that result in suitably small measurement uncertainties such that differences of 1‰ or less can be reliably detected. Inter-laboratory exercises are invaluable to assess the state-of-the art of measurement capabilities of laboratories necessary to achieve such performance criteria. National and designated metrology institutes from a number of countries recently participated in an inter-laboratory assessment (CCQM-K140) of stable carbon isotope ratio determination of bulk honey. The same sample material was distributed to a number of forensic isotope analysis laboratories that could not participate directly in the metrological comparison. The results from these studies have demonstrated that the majority of participants provided isotope delta values with acceptable performance metrics; that all participants ensured traceability of their results; and that where measurement uncertainties were reported; these were fit-for-purpose. A number of the forensic laboratories only reported precision rather than full estimates of measurement uncertainty and this was the major cause of the few instances of questionable performance metrics. Reporting of standard deviations in place of measurement uncertainties is common practice outside metrology institutes and the implications for interpretations of small differences in isotopic compositions are discussed. The results have also highlighted a number of considerations that are useful for organisers of similar inter-laboratory studies in the future.     

How Japan Can Contribute to a Peaceful World

This article discusses Japan's contribution to world peace both in the past and in the future. Japan's domestic, historical, and strategic circumstances shaped its concept of comprehensive security focused on international economic cooperation since the 1970s. Three decades of constructive relations with neighbors, including reconciliation with Southeast Asia built a strong foundation for Japan's new security role, one driven by new domestic and external imperatives. The article also documents the evolution of Japan's security policy and role in international peacekeeping, and concludes by arguing that Japan–ASEAN partnership is a key component of Japan's new security role, including permanent membership in the United Nations Security Council. In developing this new role, it is critically important that Japan engages its neighbors in ASEAN (and elsewhere) to gain their support for this new role.

LABOR FORCE PARTICIPATION AND POVERTY STATUS AMONG RURAL AND URBAN WOMEN WHO HEAD FAMILIES

This paper examines differentials in the propensity to be living in poverty among women who head families with minor children. Characteristics of mothers are examined for four subgroups: residents of central cities, suburbs, small towns, and rural areas. Using Public Use Microdata Sample data from the 1980 Census, results are presented using Multiple Classification Analysis. After controlling for the effects of mother's race, marital status, education, work status, and ages of her children, single mothers in central cities and smaIl towns have the highest rates of poverty (48% and 45% respectively), closely followed by those in rural areas (41%). Suburban single mothers are least likely to live in poverty (33%).
Results show that employment status is the strongest predictor of poverty, followed by education and marital status. A subanalysis of women who work full-time reveals major differences in earned income, with suburban women earning the highest incomes, followed by women living in central cities, then rural areas and, finally, small towns. A decomposition of this difference reveals that about two-thirds of the difference is due to pay scales, and only one-third due to the structure of occupational opportunity.     

China's corporate credit reporting system: A comparison with the United States and Germany

Corporate credit reporting (CCR), which aims at increasing trust in corporates, constitutes an intriguing, yet understudied set of regulatory institutions as it is both a regulatory object and subject at the same time. Differences in national CCR systems pose challenges for multinational companies and have increasingly become a subject of international conflicts on regulatory standards. In this context, the case of China deserves special attention since the country pursues both institutional divergence and convergence with international examples. Hence, the characterization of China's regulatory regime remains difficult. By comparing the institutional context of CCR in China to those in the United States and Germany, this paper sheds light on a specific aspect of China's complex regulatory regime. At the same time, it provides insights into the Chinese manifestation of CCR, which are important for the international business community.
